Event categories not showing up

Hello,
I currently am trying Matomo with a demo account for my software. My main interest are events since my app is not page based.
I successfully sent events from it, as I can find them back in the Real-time page:

To test, I made all of the events fall in the same category: “Game”, and I added an action name “Select” as well as a value.

Now my problem is the following: I can’t find this “Game” category in the Behaviour>Events page, the interface tells me there is nothing to display.

What did I do wrong?
Thanks for your help!

Hi @NJullienSweet
To see data in reports other than live view and visits log, you have to wait reports are generated (or data are archived):

About the Single Page Application, I suggest you track also functional page views (fake pages views ie events where the user think a new page is displayed). Matomo is indeed more based on page views than on events.
